Battery Connection - Tripp Lite APS Series Owner's Manual

Battery Connection

Connect your Inverter/Charger to your batteries using the following procedures:
• Connect DC Wiring: Though your Inverter/Charger is a high-efficiency converter of electricity, its rated
output capacity is limited by the length and gauge of the cabling running from the battery to the unit.
Use the shortest length and largest diameter cabling (maximum 9.3 mm or 2/0 AWG) to fit your Inverter/
Charger's DC Input terminals (see table below). Shorter and heavier gauge cabling reduces DC voltage drop
and allows for maximum transfer of current. Your Inverter/Charger is capable of delivering peak wattage
at up to 200% of its rated continuous wattage output for brief periods of time. Heavier gauge cabling
should be used when continuously operating heavy draw equipment under these conditions. Tighten your
Inverter/Charger and battery terminals to approximately 3.5 Newton-meters of torque to create an efficient
connection and to prevent excessive heating at this connection. Insufficient tightening of the terminals
could void your warranty.

• Warning: Do not use a wire gauge smaller than 6 AWG (4.1 mm).
• Connect Fuse: NEC (National Electrical Code) article 551 requires that you connect all of your Inverter/Charger's positive DC Terminals
directly to a UL-listed fuse(s) and fuse block(s) within 460 mm (18 inches) of the battery. The fuse's rating must equal or exceed the
minimum DC fuse rating displayed on the Inverter/Charger's nameplate. See diagrams below for proper fuse placement.
WARNING!
• Failure to properly ground your Inverter/Charger to a vehicle's chassis or earth ground may result in a lethal
electrical shock hazard.
• Never attempt to operate your Inverter/Charger by connecting it directly to output from an alternator rather
than a battery or battery bank.
• Observe proper polarity with all DC connections.
Your Inverter/Charger/s Nominal DC Input Voltage must match the voltage of your battery or series string of batteries. In a series
connection, your Inverter/Charger's Nominal DC Input Voltage must match the number of batteries multiplied by their voltage. For example,
a 24V DC Inverter/Charger would require either two 12V batteries connected in series (24 = 2 x 12) or four 6V batteries connected in
series (24 = 4 x 6).
